Personally I would avoid double glazed sealed units for a good few years yet. I feel they still have to prove themselves as to how the seal copes with vibrations and the occasional hull impact.

If I were to want to live aboard during the winter I would go for secondary double glazing in a timber frame that can be removed for the summer and also to remove condensation. Probably perspex "glass".

A number of people have good results with temporary "heat shrink" films on magnetic or adhesive mounts.

Mine is 10 years old and still in perfik condition Tony, it works well and I would never ever take a backward step of going single glazing

For several years now I've used the "cling film" type successfully. Adhesive tape is placed around the wooden frames and the film is positioned then shrunk with a hairdryer. It's a fiddly job but once you get the hang of it you can make it crease free. The cost of the pack is around £15.

Thing is, whilst it's nice to have the clear view, it's not the condensation on the glass that causes issues because normally it drains to the outside. The condensation on the frames has nowhere to go but the surrounding woodwork. Thermal break window frames are what we really need - double glazing would be the icing on that cake.

I agree, on my old boat I fitted upvc double glazed caravan units, they were light oak coloured and had no condensation issues at all. The frames were only about 7mm proud of the sides so looked ok, and were leak free
